The LWA Swarm is an aperture synthesis telescope consisting of interconnected Long Wavelength Array (LWA) stations autonomously making joint observations. In 2024, the LWA collaboration completed commissioning for the LWA-North Arm, a 64-element “swarm” station, and construction is underway to build two additional LWA Swarm stations in Arizona and Texas. By early 2026, the LWA Swarm will be a six-station long baseline interferometer, capable of arcsecond resolution imaging with millijansky sensitivity. Here we use the three-element interferometer consisting of LWA1, LWA-SV, and LWA-NA to survey 30 radio sources as candidate calibrators for the LWA Swarm. Of these 30 sources observed we find 25 viable calibrators and present images of all sources at 66 MHz. Based on the properties of the observed calibrators, we conclude that many other suitable calibrators will be available to the LWA Swarm. In anticipation of the availability of this new instrument, we provide a preliminary guide to observing and calibrating LWA Swarm data.
